摘　　要：中国经济的发展和国家能源安全的保障都对海上油气勘探提出了更高要求。如何解决勘探力度大力提升与勘探程度增加带来的成效趋势性降低之间的矛盾,是中国海上油气勘探面临的一个重大挑战。笔者在系统梳理中国海油勘探历程基础上,结合近年来勘探形势和海上资源特点,提出“资源驱动型”勘探新模式。依据对地质情况的认识程度和勘探策略的调整,中国海油40余年的勘探历程可划分为地质主导、效益导向、投资组合和集约化4个勘探阶段。其中,第一阶段钻探井数较少,对地下地质情况认识不清,以地质认识为主导实施勘探;第二阶段探井工作量有所增加,逐渐走向效益主导勘探;第三阶段探井位工作量大幅增加,是以投资组合优化勘探部署的阶段;第四阶段随着勘探走向更深、更复杂领域,多专业融合的集约化勘探成为海上油气勘探的必然选择。为解决油气储量增长要求提高与矿区勘探程度加深的矛盾,依据地下资源探明程度从新区新领域到成熟区再到滚动区的演进转化特点,从地下油气资源与地上人力资源两个维度分析,提出中国海上“资源驱动型”勘探管理模式,打破以地区为单元的管理界面,实行全海域相同演进阶段勘探区统一分类布局管理、不同演进阶段勘探区从集中到分权再到放权的勘探权限动态管理,建立以阶梯式人才激励和开放式技术管理经验交流为基础的实施保障措施。该勘探模式为中国海油近年来大中型油气田的不断发现和储量的持续增长提供了有力保障,在勘探程度不断提高情况下使勘探成效稳中有升,并将持续保障未来海上油气勘探的高质量发展。To promote economic development and guarantee the national energy security of China,higher requirements have been put forward for offshore oil and gas exploration.However,it is a major challenge for China’s offshore oil and gas exploration to solve the contradiction between the increase in exploration intensity and the decrease in efficiency.On the basis of systematically combing the exploration history of CNOOC and the exploration situation and the characteristics of offshore resources in recent years,a new resource-driven exploration model was proposed.According to the understanding of geological conditions and the adjustment of exploration strategies,the exploration history of CNOOC in the past 40 years could be divided into four stages:geology-led exploration,efficiency-oriented exploration,investment portfolio-optimized exploration,and intensive exploration.In the first stage,the number of drilling wells was small,and the understanding of underground geology was not clear.The exploration was led by geological understanding.In the second stage,the workload of exploration wells increased,and the exploration was gradually efficiency-oriented.In the third stage,the workload of exploration wells increased significantly,and exploration deployment was optimized by the investment portfolio.In the fourth stage,with exploration moving toward deeper and more complex fields,intensive exploration with multi-professional integration became an inevitable choice for offshore oil and gas exploration.In order to solve the contradiction between the increasing requirement of oil and gas reserves and the deepening exploration degree of mining areas,the evolution and transformation characteristics of underground resource exploration degree from new area,mature area,to rolling area were analyzed.From the two dimensions of underground oil and gas resources and above-ground human resources,the resource-driven exploration management model of China’s offshore oil and gas was put forward.It broke the region-based management interfa
